Definitions

• the invention relates to an adhesive based on a polymer which in Compound can be tackified with aqueous moisture, as well as its use.
• Industrial products with self-adhesive properties are from the well-known daily use, examples are the various types of films and adhesive tapes, i.a. in the Packaging, construction or furniture industry as well as in the metal, glass and automobile industry or even office products like Adhesive strips, adhesive labels or sticky notes. They mean that they are for gluing on different substrates one-sided or depending on Their special application also coated on both sides with adhesive are.
• the adhesive layer For self-adhesive adhesives, it is necessary to use the adhesive layer with a backing material, such as siliconized paper, to protect it not before use, e.g. pollution, loss of activity, or in the case of foils, the foil layers are not mutually exclusive stick together. After application, the carrier material does not fall Recyclable waste and thus represents a disposal problem.
